From a7c119bd82a1d937db5b86fcfe1d5f991469c52d Mon Sep 17 00:00:00 2001 From: Paul Blakey Date: Sun, 3 May 2020 16:45:02 +0300 Subject: [PATCH] net/mlx5e: CT: Allow header rewrite of 5-tuple and ct clear action With ct clear we don't jump to the ct tables, so header rewrite of 5-tuple can be done in place (and not moved to after the CT action). Check for ct clear action, and if so, allow 5-tuple header rewrite.
